Abstract
The disk drive device includes a base member, a hub, a bearing unit which is arranged on the base member and which rotatably supports the hub, and a spindle drive unit which drives the hub to rotate. The spindle drive unit includes a stator core having a salient pole, a coil wound around the salient pole and a magnet opposed to the salient pole. The base member includes a wire hole through which a drawing line of a wire for forming the coil passes, and a concavity formed at a bottom surface of the base member at least partly arranged radially outside the outer diameter portion of the magnet. The drawing line passes through the wire hole and is arranged along the bottom surface of the base member and connected to a wiring member at the concavity beyond the outer diameter portion of the magnet.
